Specification of Letters Patent.

Application filed December 21, 1917. 'Seria1-No.*208,229.

To aZZw/zom it may concern.

Be it known that I, HOWARD D. CoLMAN, a citizen of the United States, residing at Rockford, in the county of Vvinnebago and State of Illinois, have invented certain new and useful Improvements in Vinders, of which the following is a specification.

The object of this invention, generally stated, is to provide improved means for counteracting any tendency that may be operating to make the yarn mass being wound eccentric or tapering. While the invention is applicable to various types of winders, it is herein shown .as applied to a warping machine, such a machinebein used in winding a considerable number or warp threads upon a section beam.

hen the warper is to be operated at high speed, it is imperative. that the yarn mass be prevented from becoming eccentric, as otherwise the bounding of the heavy beam will cause destructive vibration.

After being filled, the section beam is mounted with other section beams in a slasher, in the operation of which slasher the threads are rewound from the section beams onto a-loom beam. If the yarn masses upon the section beams are tapering, the yarn will be rewound in the slasher with varying tension, causing serious trouble in the slasher and resulting in the production of imperfect warps.

In the accompanying drawings, Figure 1 is a fragmental side elevation of a warpeiembodying the features of myinvention. F igs; 2 and 3 are sectional views showing the means whereby the beam is held in place in the warper, Fig. 2 being a viewtaken on dotted line 22 ofFig. 3, and Fig. 3 being.

taken on dottedline 3 of Fig. l.- Fig.4 is

' Fig. 7 is a" sectional View showing certain gearing comprised in the mechanism. 8 is a detall view of a certain yoke and ad- .j acent parts.

Thebeam B consists .of a barrel having heads I) and trunnions b". The beam is rotatable by means of. a friction drum 122 rotatably supported in the frameworkof the .warper and-driven-by any suitable means.

The beam issupported with its yarn mass in 1381'113l1612tl contact with the-periphery of the d-rlving drum 122 by means of two arms 120 pivoted to the warper framework upon the axis 121. The trunnions may be connected to the arms 120 in any suitable manner. As the trunnions are sometimes out of -alinement, it is desirable to provide a self-alining connection between the trunnio'nsandthe arms 120. Invthe present -constructio'n,'the free end of each arm 1 20 is provided with a socket 400 in its lower side to recei've aball member 401. The surface of the ball member 401 which makes contact with the socket 400 1s a portion of asph'ere. The socket 400 is made somewhat more than semi-circular to prevent the ball member 40l"from falling out. Swivelling movement of the ballmember maybe limited in any desired manner, as, for examplefby means of a stud 402 fixed to the socket and extending into an opening 403 in the ball member. The opening 403 is large enoughto allow 'sufiicient turning movement of. the ball member.

nal adjustment with reference to the driving drum 122, the bushing 404 of each arm 120 is caused to bear against an annularshoulder 25 on the trunnionby means of anadjusting screw. 405 extending into the ball member 401. The bushing. has a flange 406 which is secured to the adjusting screw 405 by means of a 'clamp'40'T.

A latch 408 iszpivoted to each armat 409, the free end of said latch being normally held in place beneath the trunnion b by means of a coiled spring 410. The latch'is provided with a handle 411. The" free end of the latch has a beveled edge-412 so that upon relative approaching movement between the arm 120 and the trunnion 'the'latch 7 shall be pushed aside to allow -the trunnion diametrically opposite studs 415 thatlie in elongated openings 416 in the arm. The screw rod413 is rotatably mounted in a yoke or coupling'member 417 (Figs. 1, 7

. wheel.

ELI

and 8) which is pivotally mounted upon a shaft 418 extending from side to side of the warper. The screw rod 413 is interm ttently rotated to allow the arm 120 to rise as the beam fills by means including a bevel gear 419 (Fig. 7) secured to the lower end of the screw rod, said bevel gear meshing with a similar gear 420 which is rigid with the shaft 418. it will be seen that the shaft 418 causes the screw rods 413 at the opposite sides of the warper to rotate simultaneously. As will be evident from Fig. 6, the rods 413 rotate in opposite directions, one rod having a right-hand thread and the other a lefthand thread.

The shaft 418 is rotatably mounted in bearings 421 (Fig. 7) in the forward ends of two levers 422, said levers being pivoted to the warper framework at 423. The rear ends of the levers 422 carry roller studs 424 (Fig. 6) that lie within elongated openings in crank arms 425 fixed upona rock-shaft 182. Rigid with the shaft 182 is a weighted arm 427 that causes a downward pull to be exerted upon the screw rods 413.

The shaft 418 is rotated in the direction to cause the screw-rods 413 to travel downwardly in the nuts 414 by means comprising a ratchet wheel 428 (Figs. and 7) which is rigid with said shaft. Plvoted 011 the axis of the shaft 418 is an arm 429 having pivoted thereto a spring-pressed pawl 430 which is arranged to engage the ratchet The arm 429 is arranged to be swung by means of a link 431 which is pivoted to a crank pin 432 upon one end of the shaft 433 of the friction drum 122. The link 431 has a longitudinal elongated opening 434 in which is located a roller stud 435 carried by the arm 429. A tension spring 436 connected to the link and to said stud yieldingly connects the arm 429 to the link 431 and normally holds the stud 435 against the inner end. wall of the thereon.

slot 434. Rigid with the shaft 182 is a stop arm (Fig. 1) which is arranged at times to obstruct the swinging movements of the arm 429 so as to prevent the pawl 430 from turning the ratchet wheel, The arm 429 is provided'with a bar 438' which is adapted to stop against the end of the arm 437.

Anysuitable means may be provided to damp the vibrations of the weighted arm 427, as, for example, a dash-pot 439 (Fig. 1), the plunger of which is connected to one arm of a bell crank 440, the other arm of the bell crank having a pin-and-slot connection with an arm 441 that is rigid with the arms 425'and 437.

In operation, the friction drum 122 is rapidly rotated to revolve the beam B in the direction to wind the warp threads The weighted arm 427 acting through the shaft 182, the crank arms 425,

the levers 422, the yokes 417, the screw rods 413, the nuts 414, the studs 415 and the arms 120, presses the yarn mass on the beam tightly and practically unyieldingly against the drum 122. Any tendency operating to make the yarn mass eccentric is continually being resisted. To illustrate: If the yarn mass were to become slightly eccentric, the high portion, in passing between the axes of the beam and the drum would tend to force the arms 120 to swing away from the drum against the downward pull exerted through the screw rods 413, but by reason of the dash-pot 439 and the inertia of the parts, the arms 120 would not yield to such upward pressure, and consequently the high portion would be rolled down, and the yarn mass restored to cylindrical form.

As the yarn mass increases in diameter, the arms 120 are forced upwardly, thus lifting the screw rods 413, and causing the levers 422 to turn, the rear ends of said levers moving downwardly. As said levers are connected with the crank arms 425 and the latter in turn are rigid with thestop arm437, the forward end of said stop arm moves downwardly. When said stop arm has swung downwardly so far as to be entirely below the bar 438, the link 431 and spring 436 are permitted to impart one or more complete oscillations to the arm 429, thereby enabling the pawl 430 to turn the ratchet wheel 428 through the distance of one or more teeth. The screw. rods 413 are thereby turned through a partial revolution in the direction to lower said rods. The rotation of the screw rods 413 allows the weighted arm 427 to descend, thereby swinging the stop arm v437 into the path of the bar 438, and causing a suspension of operation of'the pawl 430. The mechanism thus operates intermittently to adjust the connection between the arms 120 and the pressure-applying means as the yarn mass increases in diameter. Inasmuch as the shaft 418 equalizes the rotation of .the screwrods 413 and the shaft 182 equalizes the movements of the levers 422, the upward movementsof the opposite ends of the beam are parallel, and thus the formation of a tapering yarn mass is prevented. 7

When the beam is to be removed from the warper, the arms 120 must be raised sufficiently permit of the disengagement of the'trunnions b? from thearms. After an empty beam has been connected to the arms 120, said arms must be lowered to place the beam upon the drum 122. It is therefore desirable to provide means for manually rotating the screw rods 413 to raise and lower the arms 120. The means herein shown for this purpose comprises a sprocket wheel 442 rotatably mounted upon one end frame of the warper and rigid with a crank-receiving stud 443. A chain 444 extends from the wheel 4142K) wheel 445 (Fig. '7) whichyisi rigid with the shaft 418.

ing with the trunnion; and the latch 4087 serving to hold the trunnion in place while the other trunnion is being lifted and connected to the other arm 120.

The invention is not limited to the con struction and arrangement shown, as various modifications may be made within the scopeof the invention as defined by the appended claims.
